FREDERICK G. REINEKING, OF NEW YORK, N. Y.

AIR-INTAE REGULATOR FOR GARBURETERS.

Specification of Letters Patent.

Patented July 28, 1908.

Application filed April 10, 1908. Serial No. 426,180.

To all whom it May concern:

Be it known that I, FREDERICK C.RE1NE- KING, a citizen of the United States, residing at 208 East Sixty-third street, in the city and county of New York and State of New York, have invented anew and useful Improvement in Air-Intake Regulators for Carbureters, of which the following is a specification.

Myinvention relates to an improvement in air intake regulators for carbureters; and the object of my invention is to provide means for securing great flexibility in the control of hydrocarbon motorsf I attain this object by the mechanism illustrated in the accompanying drawings, in which F1gure 1 is a section in elevation of my device, and Fig. 2 is a section in plan of my device.

Similar letters refer to similar parts throughout the several views.

Figure 1 is a section in elevation taken in the lane m n, (Fig. 2). A is the air intake regu ator chamber with passage K leading to the carbureter. B is a pin whose function is to keep the spring S from revolvin about inside the chamber A. C is an annu ar bottom rigidly fastened to the lower edge of the sldes of the chamber A. H are pins rigidly fixed to sides of the chamber A as shown and projecting inwardly from the sides of the chamber A as shown. P are air ports in the sides of the chamber A. S is a Hat s ring running around the inside of the chain er A and restin on the pins H. This spring is in the form 0 a circle except for the opening between the ends of the spring shown in the middle of Fig. 1.

Fig. 2 is a section in lan taken in the plane a: y (Fig. 1). A is t e air intake reguator chamber. B is the pin rigidly fixed to the s1de of A. C is the bottom of the chamber A. .H are the pins rigidly fixed to the sides of the chamber A. P are the air ports in the sides of the chamber A. S is the spring resting on the pins H. S is another position of the sprmgS. The pin B is not an essentral portion of my device as its only function is to steady the sprin S, and to revent the open space between t e ends of the spring S from working around opposite one of the air ports P. A cast-r lug-"or any other device which would perform the same function as the pin B would answer equally well. The pins H are not an essential portion of my device, as their only function is to keep the bottom of the spring S clear from C the bottegl of the chamber and thereby reduce the fric tional resistance to tl1e movement of the spring S away from and toward the ports P. My device would function without the presence of the pins H by letting the spring S rest directly on the bottom C, but the presence of the pins H will perhaps add to the smoothness and uniformity of the operation of my device. The spring S, instead of having a space between its ends as shown in Figs. 1 and 2, may be made with overlapping ends, in vfihich case the pin B would be dispensed wit The operation of the device is as follows:

HI) I pressure outside the chamber A thereupon becomes operative upon the spring S through the ports P, and the result is that the spring S is pushed back from the ports P and assumes the position S. The faster the engine runs, the greater becomes the vacuum inside the chamber A, and the more the spring S is pushed back from the ports P, and t c more air is admitted to the engine. In like manner, the slower the engine runs, the less becomes the vacuum inside the chamber A, and the less the spring S is pushed back from the ports P, and the less air is admitted to the engine.

I claim as my invention In air intake regulators for carbureter s, in

combination a cylindrical air intake chamber,

air ports in the sides of said chamber, one

continuous spring inside of said chamber closing said air ports, said spring at all points being free to move back away from said air
